The Mujib Reserve of Wadi Mujib is the lowest nature reserve in the world, located in the mountainous landscape to the east of the Dead Sea, approximately 90km south of Amman. The 220 square kilometers reserve was created in 1987 by the Royal Society for the Conservation of Nature and is regionally and internationally important, particularly for the bird life that the reserve supports. The Mujib valley is being developed for adventure tourism. A number of facilities have been established including a Visitors' Centre and a beach area on the Dead Sea. Experiencing Jordan's Grand Canyon involves swimming, jumping, abseiling and floating. Its red walls are filled with running water that plunges through a 15 m waterfall.
